#Regram #RG @yaleenvironment360: New research warns that the earth may be approaching several key tipping points that could fundamentally disrupt the global climate system. The troubling changes come in three forms: the runaway loss of ice sheets, changes to forests and other natural carbon stores, and the disabling of the ocean circulation system. For years, scientists have thought these dangers would only arise when global warming exceeded 5 degrees Celsius above pre-industrial levels. But the new study shows some tipping points may already have been breached at the current 1-degree C of warming. To read the full story, visit their website. Link @yaleenvironment360 bio.
